Labs !!

So i went for my dating scan, an today makes 9weeks 1 day. They called me with my labs said everything looked fine besides my liver. Levels where more elevated than they would like to see. I have never had any problems out of my liver. Is this something I should be worrying about ? They said they would continue to do blood work an keep an eye on it. But didn't say why. Has anyone else had this happen?
